And here is image of sqlite database attached file picture.
enter image description here
Here is database source. database name is "sample", and table product.
CREATE TABLE `Product` (
`ID` INTEGER PRIMARY KEY AUTOINCREMENT,
`Name` TEXT,
`Price` TEXT,
`Desc` TEXT,
`Image` BLOB
);
cursor.getBlob() returns a byte[] array, use BitmapFactory.decodeByteArray() method to convert byte array to an image . In your Product.java change the img type from Blob to byte[]. Here's a link to official documentation.

Since your problem is make your list item clickable, you can use this after init listview in activity.
lvProduct.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
}
});
position is position of that clicked item in list. So you can get that item using mProductList.get(position)
After you can get that item, now it's time to show your item up. You can use custom dialog to make it like your demo (of cause you have to create 1 more xml):
Check section Custom Dialog in this official link: https://developer.android.com/guide/topics/ui/dialogs.html
You can use listview.setOnItemClickListener or v.setOnClickListener to solve your problem.That is the most basic ,man.

i want to use google API in my app where i insert any keyword so it must autocompete and gives me the city address

i want to use google api when i enter keyword it must give me city names with that keyword i want to use this by using StartActivityForResult()
here is my code i have reached so far: but i don't know what to do next, i have the api key and i have used the key in my manifest file i just want to complete the coding part!
case R.id.linearPlace:{ startActivityForResult(new Intent(this,Location.class),CITY);
}break;
}
}
public void onActivityResult(int requestcode,int resultcode,Intent intent ){
super.onActivityResult(requestcode,resultcode,intent);
String geoName = intent.getStringExtra("");
}

Views not visible in ListView/Adapter, but are present debugging objects

I'm struggling with this problem and didn' find any solution browsing the web and lots of other similar posts in StackOverflow
No error compiling, after a serach in the app no Views are visible in the ListView (browsing both ListView and CustomAdapter objects, result items views are present, but are not shown in the app's listview)
here the code:
